Depending on your available space, you have several options. You could consider widening or lengthening the deck on its current level. Many people like to add new levels to the deck, connected by stairs. This latter method is best when you’re worried that the new decking material won’t match the old (and if the old deck is weathered at all, it likely won’t). By putting the new deck on a different level, it makes the transition less jarring and unsightly. The new level also doesn’t have to be separated by a whole flight of stairs — one or two steps will be enough. A multi-leveled deck is also great for entertaining because it offers multiple intimate spaces.
